Comparison of 3 optical navigation systems for computer-aided maxillofacial surgery.
OBJECTIVE
To compare the accuracy of 3 computer-aided surgery systems for maxillofacial reconstruction.


METHODS
Evaluation of 3 computer-aided surgery systems: StealthStation, VectorVision, and Voxim.


METHODS
The University of California, Davis, Department of Otolaryngology computer-aided surgery laboratory.


METHODS
Four fresh cadaveric heads.


METHODS
Mean target registration error.


RESULTS
The StealthStation was the most accurate (mean [SD] target registration error, 1.00 [0.04] mm), followed by VectorVision (1.13 [0.05] mm) and then Voxim (1.34 [0.04] mm). All values met statistical significance (P < .05).


CONCLUSIONS
Measurable accuracy differences were found among the navigation systems evaluated. The StealthStation was the most accurate. However, the differences are small, and the clinical significance for maxillofacial reconstruction is negligible.
